I’m going to change the model, should I keep the same size or do the sizes and fit vary according to models?

Sizing and fit are constant across the range, although different padding may give a slightly different feel. This means you can simply swap models, but we recommend using your Authorized Edea dealer to check size and fit for each new pair.  Attention ! If you change the range of collections, going from ice to roller or vice versa, check again, there may be small differences.
